i TOOTH PASTE DISPENSING DEVICE Filed June 6, 1928 Inventor Patentedoci. 15, 1929 UNITED STATES PATENT oFFlcE 'RUSSELL L. BOURKE, OFPETALUMA, CALIFORNIA TOOTH-PASTE-DISPENSING DEVICE Application filedJune 6, 1928. Serial No. 283,342.

The present invention relates to improvements in paste tube holders andhas reference more particularly to a device for dispensing tooth pastefrom a collapsible paste tube onto the bristles of a brush.

One of the important objects ofthe invention is to providea dispensingdevice of this character which may be positioned either inwardly oroutwardly of the pastel vention will become apparent during the courseof the following detailed description.'

in the drawings:

Figure l is a side elevational view of a tooth paste tube showing thedispensing attachment positioned outwardly thereof.

Figure 2 is a longitudinal sectional view through the tube showing thedispensing attachment when placed within the tube, and

Figure 3 is a detail perspective view of the spring strip comprising thedispensing attachment and 'illustrating the same in its normal coiledposition.Y

In the drawings, with reference more particularly to Figures l and 2,the numeral 4 designates a cylindrical metallic casing Vthat is formedat its forward end with a conical portion 2, the apex portion of whichis opened as shown more clearly in Figure 2. o

About the opening in the end of the tube is formed a threaded neck 5.

A relatively elongated flat strip of spring metal is wound in a iiatcoil as shown at 30 in Figure 3, and is provided at one end with anangularly disposed vlooped detent 31. This looped member 3l is disposedover the 'l threaded neck 5 of the paste tube 4 as shown in Figure 1 andthe coil spring is unwound and is disposedl rearwardly along the bottomof the tube 4, and the rear end of the spring strip is bent back inclamping engagement over the closed end of the tube as shown at 32.

Obviously the inherent resiliency of the coil spring 30 will consist incollapsing the tube t o eXtrude the paste through the discharge openingin the neck.

In Figure 2, the paste tube collapsing member is shown built into thetooth paste tube, the action of the member being the same as that whichtakes place withrespect to the construction illustrated in Figure l.

Any suitable valved cap, suchas that designated at 6 in Figure l of thedrawings, may be carried on the threaded neck of the tube to normallyprevent escape of the paste when thc tub is not in use.

The cap may be provided with a sliding valve 8, the same being normallyretained in closed position by a spring 9 and having a linger grip 10 atits outer end for moving the valve into open position.

, l/Vhile I have shown the preferred embodiment of my invention, it isto be understood that various changes in the size, shape and arrangementof parts may be resorted to without departing from the spirit of theinvention or the scope of the appended claims.

Having thus describedmy invention, what I claim as new is:

l. rIhe combination with I a collapsible paste tube provided with anormally'closed discharge neck, of means for creating an extrudingaction when-the discharge neck is open, said means comprising a normallycoiled at spring strip secured -at its forlward end to the neck portionof the tube` the other end of the strip being connected with the closedrear end of the paste tube.

2. The combination with a collapsible paste tube provided with anormally closed discharge neck, of means for creating an extrudingaction when the discharge neck is Open, comprising a normally coiledfiat spring strip havingan apertured member at one end retained inposition at the neck por- 2 sigamos tion of the tube, and a clampingmember formed at the opposite end of the spring strip and engageablewith the closed rear end of the tube, said stripbeng adapted to rollsaid rear end of the tube forwardly to facilitate the discharge of pastetherefrom.

'In testimony whereof 1 ax my signature.
